The beneficial effects of the utility model are: in said apparatus, by on used waste and old perforation casing suit and the spacing tubing string in center, in the process moving at propelling hydraulic cylinder promotion dolly, the external diameter of waste and old perforation casing obtains reparation progressively, reach industry standard and recycle, reaching the object that reduces cost.
Accompanying drawing explanation
The schematic layout pattern of this apparatus for shaping of Fig. 1.
In figure, 1-connects tailstock, 2-propelling hydraulic cylinder, 3-adpting flange, 4-dolly, 5-perforating gun limiting tool, the waste and old perforating gun of 6-, 7-travel switch, the spacing tubing string in 8-center, 9-lifting hydraulic cylinder, 10-resiliency supported wheel, 11-limiting plate, 12-travel switch, 13-load coil, 14-rolling die, 15-mold base, 16-righting wheel, 17-drive, 18-blanking hydraulic cylinder, 19-blanking travel switch, 20-frame.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
A kind of oilfield waste and old perforating gun surface apparatus for shaping, comprise frame 20, propelling hydraulic cylinder 2, dolly 4, resiliency supported wheel 10, limiting plate 11, load coil 13, mold base 15, righting wheel 16 and some groups of drives 17, blanking hydraulic cylinder 18 and blanking travel switch 19, described propelling hydraulic cylinder 2 is placed in a side of frame 20, the front end of propelling hydraulic cylinder 2 is fixedly connected with flange 3, the dolly 4 that can move in frame 20 is near adpting flange 3, the spacing tubing string 8 of horizontal fixed center on dolly, one end of the spacing tubing string 8 in center is perforating gun limiting tool 5 fixedly, the other end of spacing tubing string 8 is supported by the limiting plate 11 being fixed in frame 20, limiting plate 11 is provided with travel switch 12, above-mentioned load coil 13, mold base 15, righting wheel 16 and some groups of drives 17 are fixed in frame 20, and load coil 13 is near limiting plate 11, mold base 15 is near load coil 13, the interior stationary roll compression mould 14 of mold base 15, and the internal orifice dimension size of rolling die 14 can be adjusted, above-mentioned righting wheel 16 and some groups of drives 17 are positioned at the opposite side of mold base 15 successively, and be positioned at fixed journey system switch 7 in the spacing tubing string 8 in center frame 20 below, frame 20 base lifting hydraulic cylinders 9, the top fixed band resiliency supported wheel 10 of lifting hydraulic cylinder 9, fixing blanking hydraulic cylinder 18 in gantry base below being positioned at drive 17, the opposite side of described frame 20 is also provided with blanking travel switch 19.In addition, on above-mentioned propelling hydraulic cylinder with connecting tailstock 1.
Utilize this device as follows to used perforation casing shaping process: first, first, waste and old perforating gun 6 is installed to the spacing tubing string 8 in center and located by frock 5 through rolling die 14 and load coil 13 covers from right-hand member, object is to prevent in hot roll-in process, and the unstable and internal diameter of perforating gun changes; Then, by lifting hydraulic cylinder 9, in lifting state, object is to make perforating gun and propelling hydraulic cylinder 2, load coil 13, rolling die 14, righting wheel 16 concentric; Propelling hydraulic cylinder 2 promotes dolly 4 motions afterwards, and now waste and old perforating gun 6 also advances in the lump, and when dolly 4 touches travel switch 7, lifting hydraulic cylinder 9 falls after rise; It is waste and old when perforating gun 6 touches travel switch 12, propelling hydraulic cylinder 2 can drive waste and old perforating gun 6 to turn clockwise, load coil 13 is started working simultaneously, to waste and old perforating gun 6 heating, while waiting waste and old perforating gun 6 by rolling die 14, be subject to the active force of rolling die 14, and now within the scope of the 3-5mm of waste and old perforating gun surface temperature can reach 1100-1200 ℃, in this hot situation, be subject to revolving force and roller pressure acts on simultaneously, waste and old perforating gun surface obtains shaping reparation.Because the internal diameter of rolling die 14 is consistent with the external diameter of standard perforating gun, so the perforating gun outside dimension after shaping reparation can reach standard-required.And this process has also embodied the core of hot external pressure shaping.When dolly 4 is encountered limiting plate 11, can halt, and hydraulic cylinder 2 can drive the perforating gun 6 of repairing to move on by the spacing tubing string 8 in promotion center.Whole by after rolling die 14 shapings, also to pass through two groups of righting wheels 16, hot, lower the linearity of the perforation casing of repairing be played to corrective action again.When the perforating gun of repairing triggers blanking travel switch 19, hydraulic cylinder 2 can exit perforation casing by drive center tubing string 8, and then blanking hydraulic cylinder 18 actions, realize automatic blanking.
